Retin-A, also known as tretinoin, is a topical medication used to treat acne, wrinkles, and other skin conditions. It is available in cream, gel, and liquid forms, and can be purchased over-the-counter or by prescription.
Retin-A is a retinoid, which means that it is derived from vitamin A. Retinoids have been shown to improve the appearance of the skin by increasing cell turnover and collagen production. This can help to reduce wrinkles, acne, and other skin problems.
